Sothoryos

One of three continents in the world of Game of Thrones, Sothoryos serves as the southernmost continent above which is both Essos in the east and Westeros in the west.

Little is mentioned about Sothoryos in the books. In an interview George RR Martin described it being "unexplored" and very similiar in size and climate to Africa, including deserts and "jungly plague-ridden" areas.
